Abstract
In this study, the effect of glycerol kinase overexpression in Synechocystis sp. PCC 6803 on lipid content was investigated. The glycerol kinase overexpressing Synechocystis cells (OE) had a higher lipid content than the wild type. The OE treated with phenol up to 1â¯mM showed a slight increase in the cell biomass whereas the total lipid production increased considerably (0.39â¯Â±â¯0.012â¯g/L) as compared to that of the wild type (0.26â¯Â±â¯0.01â¯g/L). The supplementation of 12â¯g/L glycerol to BG11 medium increased the lipid content of phenol treated OE from 22 to 35% with the increase of lipid production from 0.39â¯Â±â¯0.012 to 0.69â¯Â±â¯0.035â¯g/L. The RT-PCR analysis revealed that the expression of glpK was upregulated from 1.3 to 2.4 and from 1.89 to 3.64-fold after phenol treatment and glycerol supplementation respectively.
